To all whom 'it may concern:

Be it known that I, JOHN D. BELANGER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Oil-Presses, of which the following is a specification.

My invention relates to improvements in oil presses and is illustrated in one form in the accompanying drawings, wherein- Figure l is a side elevation; Fig. 2, a front view; Fig. 3, a section along the line li- 4: of Fig. 2; Fig. 4l, a section along the line 5 5 of Fig. 3; Fig. 5, a detail view in perspective of one'of the lining strips; and Fig. 6, a plan view on an enlarged scale of one of the oil collecting plates.

Like parts are indicated by the same letters throughout the several figures.

The adjacent supporting columns A carry at their tops the yokes A1, A2, which carry the bearings A3 in which rotates the eccentric shaft A4 carrying the drive pulley A5. The connecting rod A6 engages at one end the eccentric shaft A4 and is pivotally mounted at the other upon the cross head A7 which is slidably mounted within the guides A8 which are held upon the columns A by means of the lugs A2.

The horizontal cross pieces B which are mounted upon the columns A carry the vertically disposed oil collecting plates B1, B2, which are provided upon their opposed sides with the diagonally disposed flanges B3 which are recessed to engage the solid end strips B4 and the vertically disposed parallel-sided lining strips B5 which form the Vpressure chamber B5. The columns A are held together against the cross pieces B, the oil collecting plates B1, B2, and the end strips B4 by means of the bolts B7, B5, and nuts B9.

The oil collecting plate B2 terminates in the downwardly extending flat rigid portion C to which is held the plate C1 parallel with and overlapping the lining strips B5. In opposition to the plate C1 is the flexible plate C2 which is mounted upon the bottom of the oil collecting plate B1 and serves as a continuation of the surface of the lining strips which are carried upon the plate B1. The lower extremity of the plate C is provided with the pedestal C3 in engagement with the V cylinder C4 which rests against the wedge G5 which is slidably adjustable along the base of the column A by means of the screw C5 in the lug G7. The base of the plate C2 is provided with the pedestal C8 in engagement with the cylinder C9 upon which are carried the links C10 having at the outer extremity the cylinder C11 in engagement with one end of the lever C12 which is fulcrumed about the boss C12 on the column A.

The yoke D upon the column A has the outwardly projecting screw D1 which is in adjustable engagement by means of the nut D2 with the rocking washer D5 which is in engagement with the outer end of the lever C12.

The oil collecting plate B2 is provided at its top with the upward extension E carrying the plate El which overlaps the upper ends of the lining strips B5. The upper end of the oil collecting plate B1 carries the horizontal plate E2 which overlaps the upper ends of the lining strips B5.

The endless bands of thick flexible filtering fabric F ass downward through the pressure cham er on either side bearing upon the lining strips B5 and pass upward about the outside of the pressure chamber over the rollers F1, F2, F5', F1 and F5. The rollers F1, F2, F5, are adjustably mounted upon the lever FG which is pivotally mounted upon the lug F7 upon the column A, and in engagement near its bottom with the lever F8 in connection with the lever F9 upon which is adjustably mounted the weight F10. The rollers F", F5, are rigidly and adjustably mounted to the frame worknear the top of the pressure chamber and adapted' to guide the fabric as it enters said chamber.

The plunger G which is rectangular' in cross section and in opposition to and adapted to enter the pressure chamber' B5, is removably mounted upon the cross head A7 by means' of the reinforcing plate G1 and screws G2. The cross pieces H which engage the columns A in opposed pairs and which are located at right angles to the pressure chamber, carry the frames H1 adjustably mounted by means of the bolts H2 in the slots H5, which frames are slotted at H4 to carry the slidable bearingblocks H5 in which are rotatably mounted the shafts H5 carryino the rollers H7 and intermeshing gears 5. The bolts H9 screw-threaded in the frames H1 and engaging the sliding bearings H5, operate to vary the distance bees the tween the rollers. VThe knives I- 10 project from the surface of the rollers H7 and are adapted to engage the material as it is fed between them and cut it into suit-able lengths.

The chute K having the side walls K1 is rigidly attached tothe angle bar K2 upon.

the columns A and discharges at a point immediately above the top of the pressure chamber. lThe chute K3 is rigidly attached to the angle bar Kt upon the columns A and is located beneath the oil collecting plates B1, B2, and communicates with Ythe pipe K5, whichy is controlled by a valve and discharges into the storage tank not here illustrated.

The shaftH6 carries the collar M having the lug M1 adapted to engage during its rotation the star wheel M2 to actuate the revolution counter or indicator M3.

The lining strips B5 are parallel-sided and have one side scored with the microscopic file-like corrugations P and are provided at either end with the projecting lugs P1 adapted to be engaged by suitable plates as described to hold them in position.

Itwill be evident that while I have shown in my drawing an operative device, still many changes might be made in the size, shape and arrangement ofthe parts without departing materially from the spirlt of my invention.

The use and operation of my invention are as follows: The material such as seeds orsure chamber is driven by the eccentric andL forces an intermittently moving stream of material through the ressure chamber, the friction of the material against the walls of the chamber being suiiicient to cause an enormous pressure to be exerted before motion takes place, and this pressure forces the liquids out of the solid material through the endless filtering belts of thick canvas-like fabric which cover the opposed side walls` and which travel with theA column or so-lid stream of material. The liquids are forced by the great pressure outward between the flat lining strips being aided in their travel by the tine corrugations on one side of each of the strips, being there caught by the vanes on the oil collecting plates and discharged downwardly into the oil discharge pipe. The filtering band which travels with the column of material arrests the discharge of the foots or fine particles and obviates the need of aseparate .filteringV press since the fluid is discharged through said filtering bands in aclear condition. The enormous pressure operates in a sense to weld the filadjustable weights which weights are first raised by the adhesion of the bands to the cakes, and then exert their weight to overcome this adhesion, thus stripping the cakes. The rollers interposed below the pressure chamber may be adjusted in position corresponding to the thickness of the cake and the knives on suchl rollers operate to'cut .the cakes into suitable lengths. The pressure upon the cake by the rollers is so great that slipping does not takev place and a revolution counter on the rollers indicates the number of cakes which has been discharged through the machine.

In order that, as the materialV passes through the pressure chamber and lis compressed and loses its liquid, the friction may not decrease to too great an extent, the levers in connection with the flexible lower portion of the pressurechamber w'alls are tightened, thus decreasing the cross-sectional area of the pressure chamber or slot and the thickness of the cake is thereby reduced. By this means I provide a-press which takes the crude material, removes all the liquid from itand delivers the liquid free from impurities or foots. My press, therefore, fuliils the function of both the usual oil press and the usual filtering press, and is at the time a continuously operative machine, since the reciprocatory motion of the plunger forces` a continuous cake practically without intermission through the machine andf thestream of oil andv meal cake is to all intents and purposes uninterrupted andlwill continue as. long as-raw material is fed to the machine and power applied thereto.
